Blisters are caused by a breakdown of the swimming pool gel coat, which occurs after about 15 to 20 years of use. The problem is easily and inexpensively solved by removing the existing gel coat, and replacing it with exactly the same product that was used originally. Every 15-20 years thereafter, you'll need to remove and reapply the swimming pool gel coat.

It is imperative that this be done once every 20 years. At the first sign of blisters, stains that can't be wiped away with detergent and a cloth, or algae that is able to cling to the surface, you'll know that it's time for new swimming pool gel coat. These are all indications that the non-porous gel coat has become porous and must be replaced.

What would cause the sides of your fiberglass pool to bubble up and how can you get rid of it?

Hi- There can be several reasons for blistering in fiberglass pools. If the pool is new- the chances are that it is a manufacturing defect so you should contact the manufacturer. If the pool is older- it is probably osmotic blistering which is common in fiberglass boats. For more information on this look up "osmotic blisters" on Google. The cure is usually to let it thoroughly dry out, fix the blisters, and paint with a good epoxy that will keep moisture out. Hope this is of help to you. The previous response sounde like the blisters are soft like bubbles. The blisters on my pool are hard - can't be pushed down with hand pressure.


Are sun fiberglass pools good?

I purchased one several years ago, now it has blisters through out the pool, a crack in the bottom that leaks, and one side bulges in.Sun fiberglass pools are not considered to be among the best. Regarding the previous answer: I do not believe the crack in the bottom, and the bulging side is the fault of Sun fiberglass pools. This is almost always caused by insufficient water inside the pool to equalize the pressure caused by ground water. However, there is no excuse for blisters to appear in a fiberglass pool that is only several years old.

If your pool is made of both fiberglass and cement or gunite and the sides are fiberglass but the bottom is either cement or gunite is this a fiberglass pool that was filled with cement?

No. An older (possibly better) type of Fiberglass pool was constructed in this manner, with a concrete/Gunnite/Marcite trowled bottom and Fiberglass panels at the side of the pool. Panels are caulked together along vertical joints. Actually not a bad deal, but caulked joints must be maintained. Once the concrete starts showing through at the bottom of the pool, its time to drain and resurface. Bottom of pool should be acid washed every 3-5 years to keep it sparkling and remove mold, mildew, stains. If bottom surface is chipping off, its getting close to time to resurface bottom of pool. Bottom is treated just like any concrete/gunite/Marcite pool surface. Sides are simply brushed, caulked in timely manner.


Is a fiberglass pool better than a gunite pool?

Yes, fiberglass pools have a smooth finish. Where a concrete pool was a pourus and rougher finish that gives alge something to grab on to. Also staining it. A low calcium level can pit a concrete pool, not a fiberglass, plus a fiberglass pool is more flexible,so ground movement wont crack it. In the long run the extra money you pay for fiberglass is worth it.


Is it possible to replace a fiberglass pool with a traditional in-ground pool?

Absolutely, But if you only have the land to fit a fiberglass pool, Your new gunite pool will be considerably smaller by about 1 foot all the way around. A fiberglass drop in pool is too small already, RIGHT? Kenny Kummer Brody Chemical


Is there a video on how to replaster a fiber glass pool?

Hum, not sure if you can actually plaster a fiberglass pool. The glass would have to be removed first. You will have to consult a pool builder, a company that installs fiberglass shells or a company that installs fiberglass in plastered pools - thus converting a gunite/plaster pool into a gunite/fiberglass pool. The later uses the old pool shell as the sub-grade or foundation so to speak. k


How do you get stains off plastic pool steps?

Vinyl liner pool steps are constructed of fiberglass, vinyl ester resin, and swimming pool gel coat. Staining (and blisters) occur around the pools 20th anniversary. It's caused by a breakdown of the white finish called swimming pool gel coat. Stains and blisters can only be removed by replacing the now porous gel coat with new nonporous swimming pool gel coat. Done properly, the new gel coat will last another 20 years.


Can you drain a fiberglass in ground swimming pool?

No!!! Under no circumstances should you drain a fiberglass in-ground pool. Unlike the standard in-ground pool, the fiberglass pool base is unreinforced concrete or other hard surface material that was applied directly to the soil in a thin layer. It is only there to allow the fiberglass to be sprayed on and form a hard shell. The weight of the water is what holds the fiberglass in place. If you drain the pool without refilling it immediately, you will allow external ground pressures and/or ground water to buckle the sides or bottom and you will have the fiberglass completely redone.


How do you fibreglass a inground pool liner pool?

Fiberglass pool shells are shipped in a single piece directly from the manufacturer. As a result, you don't actually linea pool with fiberglass the way you would with concrete or vinyl. Instead, installing a fiberglass pool simply means digging a hole in which to place the already completed shell.


What are the advantages of a fiberglass pool vs a gunite pool?

A fiberglass pool requires less maintenance, less repairs structurally in the future, is quick to install, and is good for smaller pools. Gunite pools are better for a pool deeper than 8 feet, custom shapes, and is a bit harder on the feet than a fiberglass pool.
